Clutch not disengaging

[Aaron IIA]

I have a SIIa six cylinder with a Holden red engine fitted. The clutch was not disengaging. I removed the gearbox and clutch. The problem appeared to be caused by both of the pins which join the clutch torque shaft being bent, resulting in lack of adjustment. The clutch friction plate has plenty of material and the diaphragm pressure plate appears in good order. The special spacer is still attached to the pressure plate. Upon reassembly, the clutch does not disengage. It appears to bind, with the tube that comes out of the gearbox to press on the pressure plate only coming out about 5mm. I installed the friction plate with the larger centre hub protrusion away from the flywheel. Is this the correct orientation? Is the pressure plate pressing on the hub of the friction plate and preventing proper clutch action? Your help is appreciated.

You appear to have the driven plate the right way. The only internal problem that I can see that would cause the release sleeve to not move enough (and it does not need to move very far, although I would think more than you indicate) would be either failure of the bearing or the release fork being in the wrong position on the splines - hardly likely if you have not had it apart.

This leaves the external linkage, probably between the slave cylinder and the release fork shaft.

Firstly, the two pins through the linking shaft should be a close fit, and must be hardened - genuine parts suggested rather than a handy bolt or pin!

Secondly, the linkage must be adjusted as outlined in the manual after fitting new parts. (I assume it is the later type since it is a Six)

It is possible that the fitting of the Holden engine has changed this setting - I can't comment on that.

Hope this helps,

The original pins were bent. I replaced them with new clevice pins. They bent on the first application of the clutch pedal. I could not source high tensile pins, so I made them from grade 12 bolts. The pins are now fine. I guess I will have to pull the gearbox out again and have a look. This is why I always check the gearbox operation before I connect the propellor shafts and install the floor. What is the later type linkage? I have only encountered one type on all of the SIIa Land Rovers that I have worked on. Unless you are referring to the early SII spring return version.

The early S2 ones, at least on paper, continued into early 2a production. And as with any Landrover, the bits fitted to the vehicle today may be earlier or later than the pattern fitted at manufacture.

But I agree - I have not dealt with the earlier type since my 1958 S2, although I can't remember what was on my 1961 2a. Must check the couple of parts donors I have here!

Is the clutch pedal moving?
A mates Series three sat for several months and the master cylinder seized!
At the end of the day any of the moving parts could be failing!
A process of elimination i think.

Good luck!
